Hi can anyone help me solve the following problem?

Determine the impulse response for each system characterized by the following difference equation.

(a) y(n) = x(n) - ay(n-1) where a is a constant

(b) y(n)= 6x(n) - by(n-1) where b is a constant

(c) y(n)= 2x(n) - cy(n-1) where c is a constant

Any help would be much appreciated.

 

You'll have to show your attempts before you get any pointers I'm afraid. Only fair don't you think?

Good point -- sorry to highjack this thread, but I am new 'round here and am hopeful that someone can help me, as I have made a full attempt at solving my own problem, which can be found here: http://forum.allaboutcircuits.com/showthread.php?p=601096#post601096

Thanks in advance.
